A. Usage and Application of Flame Plasma CNC Pipe Cutting Machine:
1. Function of CNC Pipe Intersection Cutting Machine:
CNC-CP series CNC Pipe Cut Machine is for performing pipe cutting and edge beveling:
1) Length Cutting: Cut off pipe into segments of required length;
2) Hole Cutting: Round and or elliptic holes of different diameters can be cut in the pipe body, with the effect of straight or oblique beveled rim;
3) Edge Bevel: Rim of pipe can be cut out with required radian and oblique chamfer;
4) Pipe Intersection Joint: The finished work parts delivered can be fabricated into pipe assemblies with cross intersect joint. This is the name “CNC Pipe Intersection Cutting Machine” got from;
2. Operation and Finished Workpieces Cut and Beveled from CNC Pipe Flame Plasma Cutting Machine:

2) Elliptical beveled hole cut from Wuxi JACK 5 Axis CNC Pipe Intersection Cut Machine: (Fig.2)
3) Wuxi JACK CNC-CP5-660/12 model 5 Axis machine and its finished cut pipes: (Fig.3)
4) A piece of Φ2000mm large pipe with holes cut from Wuxi JACK CNC-CP7-3000/12 model 7 Axis machine: (Fig.4)
5) Small size Intersect joint pipe assemblies fabricated from Wuxi JACK CNC-CP5-600-1400 models 5 axis Machine: (Fig.5)
B. Technical Features of Flame Plasma CNC Pipe Intersection Cutting Machine:
Based on characteristics of pipes, the machine utilizes both Oxygen fuel flame and plasma cutting technology:
1) For cutting on big thickness ferrous material: Carbon steel, especially with pipe wall thickness bigger than 50mm, and diameter larger than Φ2000mm. Flame cutting is widely used in corresponding large model machines;
2) For cutting on non-ferrous material with small to medium thickness: Alloy, Bronze, Stainless steel, especially with thickness from 3mm to 30mm. Plasma cutting is adopted;
2. CNC Control Axis in Wuxi JACK Flame Plasma CNC Pipe Cutting Machine:
Depending on diameter and thickness of pipe, together with customer demand on cut and beveled form of pipes, there are 4 options of CNC control axis configuration:
1) 3 Axis Model Machine: Equipped with the three basic control axis of X/ Y/ Z, for managing on cutting torch liner motion in 3 directions;
2) 5 Axis CNC Pipe Cutting Machine: Added with A axis and B axis, for controlling cutting torch tilting along pipe length and radius direction, so that beveling can be acquired on pipe rims and holes cut:
X/ Y/ Z/ A/ B axis of Wuxi JACK 5 Axis Machine: (Fig.6)
3) 6 Axis Model: Added with V axis for managing on cutting torch linear motion along large pipe radius direction, catering for large diameters pipe;
4) 7 Axis Model: Added with W axis for moving workpiece supporting units (Friction roller group) along pipe radius direction, so that large and super large size pipes can be cut reliably:

C. Wuxi JACK Breakthrough on Developing High Quality Mature Product of Flame Plasma Large 7 Axis CNC Pipe Cut Machine:
1. Before the year of 2010, the mature product of machine on CNC control pipe cutting in the industry and market, is for cutting pipe with maximum diameter of Φ1200mm: 3 Axis model was mainstream product at that time; 5 Axis model just saw its inception;
2. From 3/ 5 axis to 7 Axis: In the year of 2012, Wuxi JACK took the lead in developing large model complicated control, aiming on cutting pipes with the max. diameter of Φ3000mm, in the form of 7 Axis control, opening a new era for CNC-CP series CNC Pipe Cutting Machine:

3. Application: This kind of advanced technology 6 Axis and 7 Axis large size machine are widely used in industries of Oil/ Gas Transportation / Petrochemical/ Pressure Vessel, etc.
4. Wuxi JACK Position: Nowadays, CNC-CP series machine designed and made by Wuxi JACK are welcomed by customers both in China and Overseas, and gain high recognition from customers.
D. Category of Wuxi JACK Flame Plasma CNC Pipe Flame Plasma Cutting Machine:
1. General Guideline on Selecting Models of CNC Pipe Cutting Machine:
Generally speaking, as Rule of Thumb:
1) 3 Axis model is applied for cutting on small pipes with simple process: Just cut and straight edge bevel, suitable on the max. diameter of Φ660mm;
2) 5 Axis model is applied for cutting on medium to medium large pipes: Length cut and slant bevel, suitable on diameter from Φ660mm to Φ2,000mm;
3) 6 Axis and 7 Axis models are applied for cutting on large size (Diameter and pipe wall thickness) pipes, suitable on diameter from Φ2,000mm to Φ3,000mm. Especially when pipe diameter grows larger than Φ2,500mm, 7 axis control is a must to get satisfactory cutting performance;
2. Models: Based on diameter of pipes, standard model of CNC Pipe Cutting Machine falls into 4 ranges, as is indicated in below table;
3. For length of the pipes being cut, standard size is 6m, 9m and 12m. And, we can design and produce non-standard size of machine based on customer needs.
